What is the density of a 6 g of pure copper with a volume of 12 mL?
a 0.25 g/mL
b 1.5 g/mL
c 2.3 g/mL
d 0.5 g/mL

Answers

Answer 1

Answer:

The density of copper is 0.5 g/mL

Explanation:

Given data:

Mass of copper = 6 g

Volume of copper = 12 mL

Density of copper = ?

Solution:

Formula:

d = m/v

d = density

m = mass

v = volume

d = 6 g/ 12 mL

d = 0.5 g/mL

Thus, the density of copper is 0.5 g/mL

Answers

Answer:

A. Atoms gain, lose, or share electrons to achieve a full valence shell

Explanation:

The octet rule is best explained as the process in which atoms lose or gain or share electrons to achieve a full valence shell.

In this process bonds are formed when there is an attraction between the two substances. For electrovalent compounds, an atom will lose electrons or gain electron to form an ion, the electrostatic attraction causes the bond formation. Covalent compounds, form by sharing of electrons.

Therefore, the octet rule is attained when atoms gain full valence configuration.

Tendency of an object to float

Answers

Answer:

Buoyancy is the ability or tendency of an object to float in a fluid: a liquid or a gas. This happens because fluid pressure increases with depth. According to Archimedes' Principle, the buoyant force on a submerged object is equal to the weight of the liquid displaced by the object.

Calcium nitrate and calcium carbonate are both ionic compounds.

Calcium nitrate mixed with water behaves as an electrolyte.

Calcium carbonate mixed with water does not behave as an electrolyte.

Explain, in terms of solubility and movement of ions, this difference in behaviour​

Answers

Answer:

Calcium nitrate is soluble in water and dissociate into ions whereas calcium carbonate is insoluble and water and do not form ions.

Explanation:

An electrolyte is a substance which conducts electricity in molten form or when dissolved in water.

The ability of an electrolyte to conduct electricity is due the movement of charged particles called ions. The ions are of two types: negatively charged ions called anions and positively charged ions called cations.

Calcium nitrate is a soluble in water, and when dissolved in water produces two ions; negatively charged nitrate ions,NO₃⁻, and positively charged calcium ions, Ca²⁺. These ions enable it to conduct electricity.

Calcium carbonate on the other hand is insoluble in water, and thus, do not produces any ions capable of carrying current.

Isopentyl acetate is the molecule largely responsible for the aroma and taste of bananas. It is made up of carbon, hydrogen, and oxygen. Combustion of a 3.256-g sample of isopentyl acetate produces 7.706 g CO2 and 3.156 g H2O. Using these results, what is the correct empirical formula for isopentyl acetate?

Answers

Answer:

Explanation:

7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C

= 2.1 g of C .

This will be contained in 3.256 g of isopentyl acetate

3.156 g of H₂O will contain 2 x 3.156 / 18 g of H

= .351 g of H

This will be contained in 3.256 g of isopentyl acetate

Rest will be oxygen

amount of oxygen in 3.256 g of isopentyl acetate

= 3.256 - ( 2.1 + .351 )

= .805 g

ratio of C , H , O in isopentyl acetate

= 2.1 g : .351 g : .805 g

2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles

= .175 : .351 : .05  ratio of moles

= 3.5 : 7.02: 1

= 7 : 14 : 2

If the mass is 7150 kg, and the
acceleration is 2 m/s2, then what is the
force?

Answers

Explanation:

f= ma

f= 7150 *2

f= 14300N

The force will be equal to 14300N when the mass is 7150 kg and the

acceleration is 2m/s².

What is force?

Force is an external agent that can change a body’s state of rest or motion. Force has a direction and a magnitude so it is a vector quantity. The SI unit of force is Newton and the unit used is Kgm/s².

Force can change the state of a body from rest to motion and can accelerate the speed of a moving body.  The direction of a moving object can be changed by applying force.

The force is expressed by the product of the mass (m) and acceleration (a) of an object. The mathematical equation for force can be expressed in the form of:

F = ma

Given, the mass (m) = 7150 Kg and acceleration (a) = 2 m/s²

Then, force, F = (7150 Kg) × (2 m/s²)

F = 14300 Kgm/s²

or, F = 14300 N

Therefore, the force of the object will be equal to 14300 N.

Number of neutrons :

Argon=22

Boron=6

Further explanation

There are two components that accompany an element, the mass number and atomic number

Atoms are composed of 3 types of basic particles (subatomic particles): protons, electrons, and neutrons

The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.

Atomic number = number of protons = number of electrons ⇒ neutral number

Atomic mass is the sum of protons and neutrons

Atomic Number (Z) = Atomic mass (A) - Number of Neutrons

Argon has an atomic number of 18 and a mass number of 39,948

number of neutrons =

[tex]\tt 39.948-18=21,948\approx 22[/tex]

Boron has an atomic number of 5 and a mass number of 10,811

number of neutrons =
